This invention relates to improvements in humidifying and ventilating apparatus; and especially to' a. humidifying appliance adapted to be employed in conjunction with a heater orradiator in dwellings, industrial establishments and other places for the pur pose of moistening the air and maintaining the circulation thereof.

An object oit the invention is to provide a device of simple construction, inexpensive to produce and operate, and reasy to install at any convenient point, for the purpose of increasing the aqueous content ot the atmosphere to the extent desired. 'llhesobjects and advantages of the invention are set forth in the accompanying description and drawing but the disclosure/is illustrative only, and alterations in the shape, size and arrangement of the various parts may be madeu without going beyond the principle othe invention or exceeding the scope of the appended claim.

@n the drawing:

Fig. 1 is a side view, partly in section,

according to this invention, mounted and in readiness for use;

h lhig. 2 is a side elevation of the humidifier itself; and

Fig. 3 shows a modification of the device of Fig. 2.

rlhe saine numerals identify the same parts throughout.

The entire apparatus comprises a hood or cover 1 for a heater or radiator 2; and the hood supports a casing 3 in which the humidifying device is placed. may be mounted on the to 'of the hood or the side, and the hood will e provided with an air inlet opening d and an outlet open-y ing 5; -with the casing so disposed that air owing through the outlet 5 passes through the casing 3. Within the casing is an electric motor 6, the frame of which is carried by a post 7, and on the the shaft 8 of this motor in the casing 3 is a fan 9. Between 'llhis casing' 12 to which is made fast the end of a water supply pipe 13. rllhe edge of the plate is bent out in a radial plane to form a flange as shown at ld, and the end of the pipe 13 is bent down to deliver water upon the conical surface of the plate 10, between the hub 1l andthe Hangs 1li. Hence, as the' fan and plate revolve, the water lowing down on the plate 10 towards the shaft 8 will be impelled by centrifugal force towards the dange and thrown outward in inely divided particles to be taken up by the air drawn through the casing 3 by the tan and spread throughout the atmosphere of the room in which the apparatus is situated.

` llt desired, the water supply pipe may7 be arranged to deliver to the concave side of the distributor 10, as shown on `lig.. 3, where the bracket 15 mounts the end 16 of the supply pipe in position to discharge the water against the plate 10, near the center thereof. 'llhe operation of this form is of course the same.

'llhe casing 3 may have a trough or groove 17 therein, to collect the drip from the plat/e 10 land allow it to drainout through a pipe i8. 'llhe pipes or conduits 413 and 18 can be provided with suitable valves -or stopcocks, and the pipe 13 may be connected either to a city water pipe or spigot, or to a small pump driven from any available source of power. 'lhe water may be used over by pumping it back to the casing 3. i'

Ilhe apparatus is therefore quitef simple and capable of being operated at little cost. llt will make an ordinary radiator heat much. more than the usual space served by the radiator. lt can oft course be utilized with 0r Without a heater orradiator, since the fan and distributor plate make a complete unit which can be set up anywhere and connected to operate in the manner required. The device not only moistens air but also keeps it circulating, thus insuring a complete supply of fresh moist air as it may be needed, and at a temperature which of course can be controlled by regulating the heater itsel.

Having described my invention, what I claim to be new and desire to secure and protect by Letters Patent of the United States is:

A humidiying device comprising a heat` er, a hood thereover, the hood having lan inlet and an outlet opening, a casing surrounding the outlet opening on the exterior of the hood, a motor in saidcasing, the motor having a shaft, a fan on said shaft, a cone-shaped distributor plate between the motor and the fan, said plate presenting its convex side towards the fan, said fan and motor being so disposed that the fan and the distributor plate are between the motor and the hear, a bracket on the motor, and afsupply pipe held by the bracket to deliver Water upon the convex surface of the plate.

in testimony whereof i admin my signature.
